THEODORE G. THORMODSON, F HANSKA, MINNESOTA.

PNEUMATIC CONVEYER.

To all whom it may concern:

Be it known that I, 'Tr mononn G. Tnon- MODSON, citizen of the United States, residing at Hanska, in the county of Brown and accessible from any point throughout the length thereof.

Another object of myinvention is to pro vide a conveyer whichis formed of a plurality of lnterchangeable sections whereby the same may be adjusted to any desired 3 length.

A still further object of my invention is l to provide a means for connecting the various sections of the conveyor when it is desired to use the same.

It is awell known fact to those skilled in the art that the conveyers used at the present day are in most cases continuous throughout their length, the interior of the same being only accessible from either end,

and when used in connection with fine particles of material, as in use with ensilage cutters, these small particles, being slightly moistened, cling to the interior surface of the conveyer, and in time will tend to clog up and prevent the efiective operation of the device, this necessitates the taking apart of the conveyor in most cases and scraping the interior of thesame. As has been stated hereinbefore the object of my device is to overcome the above objections and provide a means whereby access may be gained to the interior of a conveyer throughout any point of its length, and that the same may be closed efiectively at this point and prevent interference of the operation of the device. 7

The valuable feature of my invention resides in the provision of aconveyer formed in the manner above set forth and consists preferably in the construction, combination and arrangement of parts hereinafter more Specification of Letters Patent.

Patented Feb. 12, 191%.

Application filed July 2, 1914. Serial No. 848,641.

fully set forth in the specification and illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a blower provided with my improved pneumatic conveyer.

Fig. 2 is a transverse sectional view taken "on the line 2-2 of Fig. 1.

Fig. 3 is a like view showing one of the hinged closures in open position.

ig. 4 is a front elevation of a section of my improved conveyor. i

Fig. 5 is a fragmentary side elevation of the same. i

. Similar reference characters indicate similar parts throughout the various views of the drawings.

Referring more particularly to the drawings in which the preferred embodiment of my invention is illustrated, the numeral 1 indicates the casing of a blower or other air propelling device, said blower receiving. its

power from the belt 2 which drives the pulley 3. Said blower. l is mounted on a base 4 which may be placed at any convenient point, the above being constructed in the conventional way and having no bearlng upon my invention.

In my improved conveyer I provide a plurality of tubular sections 5, each of said sections 5 being provided on their outer perpheries with angle irons 6 and 7, said angle irons 6 and 7 being bolted or otherwise disposed in. spaced relationupon the outersur faces of said sections 5. For the convenience I shall describe said sections, it being understood that the other sections are constructed similarly.

The said angle irons 6 and 7 disposed in spaced relation upon the sections 5 abut similar angle irons upon the adjoining section or sections and are secured together by means of splice bars or plates bars or plates 8 being shown in Fig. 4:.

To gain access to the interior of each section of the conveyer, I provide in each section an opening 9, said opening 9 being closed by a door 10, said door being preferably arcuate in contour and conforming to the configuration of the tubular conveyer sections 5. Said door 10 is provided at convenient points thereon with angle bars 11,

purpose of only one of the to advantage 8, said splice 13 being bolted or otherwise secured to one of the angle bars, namely 6, said lugs 13- and angle bars 11 providmg hinges upon which thedoor is swung.

Theside of the door 10 which is remote from the hinged portion thereof is upturned to provide a longitudinal flange 14E,

said flange ll being adapted to engage the angle bar upon the section 5,-when the door is in a closed position, which has been shownto advantage in Figs. 2 and 4:; The

said up-turned flange 14- and anglebar 7 are apertured, the apertures therein'being adapted to register as shown at 15 in Fig. 1, and a cotterpin or other suitable securing means 16 is engaged therein, for the purpose of preventing the door 10 from accidentallyopening.

From the above it will be seen that the angle bars 6 and 7 perform a dual function, in that the same provides means for reinforcing'the sections 5, also a means for hinging the door, and that it can be readily appreciated that they provide a simple and effective means for joining the adjacent edges of'the adjoining sections of the conveyer. The shape'of the-flange 14: and the reinforcing angle bar-7 prevent the door 10 from passing into the opening9 below the interior surface 17' of the conveyer sections andforming an obstruction'which would collect the finer particles of material which was being conveyed through the eonveyerjv As shown in Fig. 2 this door is flush with the interior surface 17 heretofore referred to,

thereby preventing the joint between the d'oorand the edges of the opening 9 from fbrminga ridge or obstruction, collect materialf and prevent the effective operation of the device.

may be continued slightly beyond the marginal edges of the sections 5 ,on to the ad joining section, and bolted or otherwise secured'thereto, thisbeing merely an optional matter for the manufacturer of. the same to decide. It will-be readily understood that I do not desire to limit myself to the shape of the conveyer tube as shown in the drawsired to form the same.

ingsas the same may be square, hexagonal or any shape which the manufacturer de- From the above it will be readily appreciated by those skilled in the" art that I' have provided a simple, cheap and effective means for attaining the objects which I have hereinbeforeset forth, and. that when it is desired to gain access to the interior of any one or all of the sections of my improved conveyer it is only necessary to open.

the angle bars 6' and 7 one or all of the doors 10, said doors 10 being formed of such a size as to open as large a surface of each section 5 as is practicable,

so that the entire interior surface of each sectionispracticably accessible from the exterior of the same. As is shown in Fig. 1 theconveyer tubes 5 are secured to a neck 2 which extends tangentially from the blower 1 and serves as a means for connecting, the conveyerwith the blower.

If it' isso' desired the sections v5 of the conveyer may be made in such a manner-as to allow the adj oining end's of the twosections to overlap 1 or engagebyslipping one within 'theether, andthen securing 'the same b the angle irons6and 7 and the plates 8, ow: ever, the manner in which the adjoining marginaledges ofthese sections are connectedis a matter which will 'be'deteianined in practical fields, and which has no bearing upon the-invention asnow'set forth, the only feature of said joining means is the provision of the'angle irons6 and7 and the plates. j i From theabove description-taken in connection with the accompanying drawings it 7 is thought that a thorough understanding of my invention can behad'yand theright is reserved by me 'to make such changes in the details of'construction thereof which shall not depart from the spirit and scope ofthe v appended claim. 7 Having thus describedmy invention, what I claim and desire to secureby Letters Patent is i In a portable convey-er tube, the combination of a section having an elongatedopening formed therein, longitudinally extending angle irons fixedly mountedjupon said section uponopposite sides of said'opening, the outwardly extending walls' of' the angle irons extending in planes substantially at right-angles to each. other, brackets fixedly mounted upon the inner surfaces of one wall of one angle iron, a door of substantially the sameisize as the opening in said section, angle bars-fixedly mountedupon the" outer surface of'said door, oneend' of each angle bar beingpivotally secured to saidbrackets, one edge of said door being bent outwardly at substantially right angles to form a longitudinally extending flange; .the remaining ends of said angle bars abutangle irons for holding'the door against accidentally opening, the remaining edge of the door fitting under said brackets for resisting upward movement, whereby said angle bars Will reinforce the door for holding the same against inward or outward urging action, thus forming a tight closure for the opening of said section.

In testimony whereof I aflix my signature 1n presence of two Witnesses.
